An Electromagnet is a means to change electrical energy into Magnetic Energy.
The components of an Electromagnet are a coil of wire wrapped around an iron/steel core and provided a flow of negative charges.
If you change the direction of Electricity, you will change the Poles of the Electromagnet.
Coils vs Magnetism of Electromagnet
Electric Motor
An Electric Motor uses Electromagnets to attract and repel against regular magnets to produce a spinning motion.
Brushes allow electricity to the Commutator that is attached to the Coils.
As the Commutator spins with the axle and coils, the Commutator allows each coil to receive the correct electricity direction to become an electromagnet to attract or repel against each magnet to continue spinning.
